The haul included 39 motorcycles, including a number of children's models, helmets and clothing, virtually stripping the showroom on Bromfield Industrial Estate.

Tony Gush and his business partner Steve Morgan have been devastated by the break-in, which has left them with no stock over Christmas.

Thieves broke in by forcing open security gates and roller shutters sometime between 5.30pm on Sunday and 8am on Monday.

Police are studying CCTV footage and have appealed for information.

DC Dave Pickard, of Mold CID, said the raid followed a similar burglary hours earlier in Llandrindod Wells, when nine motorcycles had been stolen.

'We are looking at both incidents,' he said. 'In the Llandrindod Wells break-in the suspects are from Merseyside.' In the Mold raid, thieves cut telephone wires to the premises, which also affected two neighbouring businesses.

DC Pickard said the break-in had been carried out by professionals who had specifically targeted the premises.

He revealed the showroom had been raided before by thieves who had broken in through the roof.

On this occasion clothing had been taken. nAnyone with information should contact DC Pickard at Mold CID on 0845 6071002 or Crimestoppers, confidentially, on 0800 555111.
